Abstract

A storage bag shifts between a flat configuration with first and second sidewalls positioned adjacent to each other, and a stand-up configuration with the sidewalls separated. In the stand-up configuration, the bag has a substantially flat base (i) formed by the bottom portion of the first and second sidewalls, and (ii) outlined by at least one of the shift regions of the sidewalls. An angle α is defined between each of (i) the first shift region of the first sidewall and an adjacent edge of the bag and (ii) the first shift region of the second sidewall and an adjacent edge of the bag, and (b) a differing angle β is defined between each of (i) the second shift region of the first sidewall and a bottom edge of the bag and (ii) the second shift region of the second sidewall and the bottom edge of the bag.

First claim

We claim:

1. A storage bag comprising:
(A) a first sidewall having (a) a top edge, (b) a bottom edge, and (c) a bottom portion, the bottom portion being adjacent to the bottom edge of the first sidewall, and the bottom portion including (i) at least a first shift region and (ii) at least a second shift region, about which the bag is capable of shifting, each of the shift regions extending a distance along the first sidewall, and at least one of the shift regions comprising one of a score line, an indentation, and a crimp formed into the first sidewall; and
(B) a second sidewall having (a) a top edge, (b) a bottom edge, and (c) a bottom portion, the second sidewall being connected to the first sidewall, the bottom portion being adjacent to the bottom edge of the second sidewall, and the bottom portion including (i) at least a first shift region and (ii) at least a second shift region, about which the bag is capable of shifting, each of the shift regions extending a distance along the second sidewall, and at least one of the shift regions comprising one of a score line, an indentation, and a crimp formed into the second sidewall,
wherein the bag shifts between (a) a flat configuration with the first and second sidewalls positioned adjacent to each other, and (b) a stand-up configuration with the first and second sidewalls separated from each other, such that, in the stand-up configuration, the bag has a substantially flat base that is (i) formed by the bottom portion of the first sidewall and the bottom portion of the second sidewall, and (ii) outlined by at least one of the shift regions of the first sidewall and at least one of the shift regions of the second sidewall, and
wherein (a) an angle α is defined between each of (i) the first shift region of the first sidewall and an adjacent edge of the bag and (ii) the first shift region of the second sidewall and an adjacent edge of the bag, and (b) an angle β is defined between each of (i) the second shift region of the first sidewall and a bottom edge of the bag and (ii) the second shift region of the second sidewall and the bottom edge of the bag, such that (i) each angle α relates to a respective angle β to facilitate the shifting of the bag between the flat configuration and the stand-up configuration, and (ii) each angle α differs from each angle β.

2. The storage bag according to claim 1 , wherein at least one of the shift regions of the first sidewall and at least one of the shift regions of the second sidewall are one of changes in elevation and changes in thickness in portions of the respective first and second sidewalls of the bag.

3. The storage bag according to claim 1 , wherein (i) the at least a first shift region of the first sidewall includes shift regions that extend from near a first corner of the bottom edge of the first sidewall, and (ii) the at least a second shift region of the first sidewall includes shift regions that extend from near a second corner of the bottom edge of the first sidewall, and
wherein (i) the at least a first shift region of the second sidewall includes shift regions that extend from near a first corner of the bottom edge of the second sidewall, and (ii) the at least a second shift region of the second sidewall includes shift regions that extend from near a second corner of the bottom edge of the second sidewall.

4. The storage bag according to claim 1 , wherein the first sidewall further includes an interlocking closure structure and the second sidewall further includes an interlocking closure structure, the interlocking closure structure of the first sidewall being configured to interlock with the interlocking closure structure of the second sidewall to seal an opening of the bag.

5. The storage bag according to claim 1 , wherein at least one of the bottom portions of the first and second sidewalls comprises a visually distinct texture to facilitate a user in the shifting of the bag.

6. A storage bag comprising:
(A) a first sidewall having (a) a top edge, (b) a bottom edge, and (c) a bottom portion, the bottom portion being adjacent to the bottom edge of the first sidewall, and the bottom portion including (i) a first shift region about which the bag is capable of shifting, the first shift region extending a distance along the first sidewall, (ii) a second shift region about which the bag is capable of shifting, the second shift region extending a distance along the first sidewall, (iii) a third shift region about which the bag is capable of shifting, the third shift region extending a distance along the first sidewall, and (iv) a fourth shift region about which the bag is capable of shifting, the fourth shift region extending a distance along the first sidewall, wherein at least one of the first, second, third, and fourth shift regions of the first sidewall comprises one of a score line, an indentation, and a crimp formed into the first sidewall; and
(B) a second sidewall having (a) a top edge, (b) a bottom edge, and (c) a bottom portion, the second sidewall being connected to the first sidewall, the bottom portion being adjacent to the bottom edge of the second sidewall, and the bottom portion including (i) a first shift region about which the bag is capable of shifting, the first shift region extending a distance along the second sidewall, (ii) a second shift region about which the bag is capable of shifting, the second shift region extending a distance along the second sidewall, (iii) a third shift region about which the bag is capable of shifting, the third shift region extending a distance along the second sidewall, and (iv) a fourth shift region about which the bag is capable of shifting, the fourth shift region extending a distance along the second sidewall, wherein at least one of the first, second, third, and fourth shift regions of the second sidewall comprises one of a score line, an indentation, and a crimp formed into the second sidewall,
wherein the bag shifts between (a) a flat configuration with the first and second sidewalls positioned adjacent to each other, and (b) a stand-up configuration with the first and second sidewalls separated from each other, such that in the stand-up configuration, the bag has a substantially flat base that is (i) formed by the bottom portion of the first sidewall and the bottom portion of the second sidewall, and (ii) outlined by at least one of the shift regions of the first sidewall and at least one of the shift regions of the second sidewall, and
wherein (a) an angle α is defined between each of (i) the first shift region of the first sidewall and an adjacent edge of the bag, (ii) the third shift region of the first sidewall and an adjacent edge of the bag, (iii) the first shift region of the second sidewall and an adjacent edge of the bag, and (iv) the third shift region of the second sidewall and an adjacent edge of the bag, and (b) an angle β is defined between each of (i) the second shift region of the first sidewall and a bottom edge of the bag, (ii) the fourth shift region of the first sidewall and the bottom edge of the bag, (iii) the second shift region of the second sidewall and the bottom edge of the bag, and (iv) the fourth shift region of the second sidewall and the bottom edge of the bag, such that (i) each angle α relates to a respective angle β to facilitate the shifting of the bag between the flat configuration and the stand-up configuration, and (ii) each angle α differs from each angle β.

7. The storage bag according to claim 6 , wherein the first sidewall further includes a horizontal shift region that extends from a first edge of the bag to a second edge of the bag, with the first and second shift regions of the first sidewall extending from a first corner of the first sidewall to the horizontal shift region of the first sidewall,
